A 2024 radiometric survey of thorium ground concentration in the Narryer region of Australia, conducted by the WA Government. The grid has a cell size of approximately 20 meters and shows thorium concentration in parts per million. The data consists of 415,090 line-kilometres of data acquired at 100m line spacing and 50m terrain clearance.
Use Cases
- Map subsurface geological structures based on thorium concentration variations.
- Identify potential mineral deposits based on radiometric signatures.
- Conduct environmental baseline studies based on natural radioactive element distribution.
- Validate geological models based on processed gamma-ray spectrometric data.
Strengths
- 415,090 line-kilometres of survey data provides substantial spatial coverage.
- Data processed via standard methods and quality-checked by GA geophysicists.
- High-resolution grid with a cell size of approximately 20 meters.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to data_gov_au.
